Nothing should hurt that bad. I remember when T400 1st came out in Mexico about 2004. I bought some and used it as long as I could. It hurt so fucking bad I could hardly function. Wanting it to be real, I did a total of about 4 injections all with severe pain. About 2 weeks later, my appendix blew up and was in the hospital for a week. Coincidence or not? Toss that shit bro, shots aint supposed to hurt like that. You're body is telling you something
